Option (D) is incorrect.
        
                    
T
he net acceleration is always directed towards the center in uniform circular motion, it's not always the case for non-uniform circular motion. 
In non-uniform circular motion, there's a tangential acceleration component in addition to the centripetal acceleration, meaning the net acceleration is not solely along the radius towards the
 center.

Which of the following statements not true?a)The velocity vector of a ...
Option A: True. The velocity vector of a particle at any point on its path is always tangent to the path at that point, as velocity represents the direction of motion.
Option B: True. For a particle in uniform circular motion, the centripetal acceleration points towards the center. Over one complete cycle, the acceleration vectors cancel out, resulting in an average acceleration of zero (null vector).
Option C: True. The net acceleration in uniform circular motion is centripetal acceleration, which always points towards the center of the circle along the radius.
Option D: Not true. This statement is incorrect because it implies that the net acceleration in all types of circular motion is always radial. While in uniform circular motion, the acceleration is purely radial, in non-uniform circular motion, there is an additional tangential component of acceleration due to the change in speed. Thus, the net acceleration in such cases is not always directed towards the center.
